AbstractUser interfaces are omnipresent in daily consumer goods, whether it is in the usage of brown goods or the access to the menu of a DVD player, as well as in the Ambient Assistive Living services that are being established like for example in the OASIS project and which will be provided to older people. Considering the growing number of older people and the directly linked increasing number of disabilities that will appear accordingly, OASIS project has taken the step to consider accessible user interfaces (UI) from the very beginning using a variety of interaction technologies. In addition, it will also have its interfaces assessed by using the assessment tools provided by the ACCESSIBLE project that focuses on ensuring web, desktop and mobile interfaces are fully accessible from the very beginning, without any adjusting afterwards.
